There's no indication on that page that that issue with ndis.vxd was
related to CPU speed.

I did a quick google search and found quite a few posts from people
having problems installing win98/se on hi-end machines though

Again there is way more going on with "hi-end" machines than just the
cpu speed. I shouldn't have to point out that chipset support,
display adapter support, hard drives 137 gb, and lots of installed
memory is going to be the problem in that case - not the CPU speed.

There seems to be a genuine conspiracy around here to plant the idea
that there is a known issue with win-98se and CPU speed greater than
some value.
